Feat: Wails (v2)

[rolznz]

This PR allows NWC to be run in multiple formats:

• HTTP server
• Wails desktop app

The LN backend can be initialized after startup, allowing the user to choose and configure their node.

THIS IS NOT BACKWARD COMPATIBLE. POSTGRES IS BEING REMOVED, SQLITE REQUIRES A FRESH DB.

Post-merge: update Github to point at master branch

TODOs:

• [x] merge single-user cleanup PR
• [x] React app now doesn't build if wails files don't exist - maybe we do need to do a dynamic import for the request code? - @bumi
• [x] fix redirection to setup page (currently can't even visit about page) - fixed in onboarding branch
• [x] fix redirection when node is not started yet (should not be able to access apps) and when node is not setup (should not be able to access start) - fixed in onboarding branch
• [x] handle requests made before LNClient starts up - should return an error code if svc.lnClient is nil - @im-adithya - cannot be done
• [x] fix failing workflow build - @frnandu
• [x] remove legacy handling for apps without permissions - Roland
• [x] Service refactor - Roland
  • [x] move "api" methods to separate object (Currently in "Service" object) - Roland

• [x] Add logging for wails app @bumi
• [x] Add encryption of config table - Bumi
• [x] Make sure created_at/updated_at fields in DB are still working - Roland

• [x] Infinite retry for unable to connect to relay
• [x] Do not try to decode keysends - Roland
• [x] Address https://github.com/getAlby/nostr-wallet-connect/issues/231 - @im-adithya (https://github.com/getAlby/nostr-wallet-connect/pull/235/commits/5ee1dfcfa64456ebaafcbd0128c7ca7b281d257a)
• [x] Remove ReceivedEOS check - wait for eos before executing next go subroutine - Adithya
• [x] Add new master branch and change target branch to master. main will not be updated
• [x] graceful exit when closed
• [x] Remove Alby LNClient - Roland
• [x] Remove multi-user code - Roland

• [x] Setup page
  • [x] Breez
  • [x] LND
• [x] document how to do production build
• [x] better way to determine if launched in wails mode - there should be 2 entrypoints, with correct one set at build-time
• [x] test production build
• [x] frontend request abstraction for wails vs http
  • [x] basic abstraction
  • [x] support all request methods
  • [x] body in the request
  • [x] error handling
• [x] breez - create user if doesn't exist
• [x] wails go request router
• [x] remove dependency on echo from LND LNBackend
• [x] review if changes to dockerfile are needed due to go build tags - not needed
• [x] add breez api key to setup form
• [x] make Windows version of build/run commands (cp in yarn commands do not work)
• [ ] testing
  • [ ] HTTP app type
  • [ ] LND
  • [x] Breez
  • [ ] WAILS app type
  • [ ] LND
  • [x] Breez
• [ ] manual build testing
  • [x] Linux
  • [ ] Mac
  • [x] Windows
• [ ] release with manual wails builds available for
  • [ ] Mac
  • [ ] Linux
  • [ ] Windows

To move to seperate issues:

• [ ] improve onboarding page UI
• [ ] add NIP-47 Supported Methods for Breez (e.g. lookup invoice right now only supports payment hash and only works for settled invoices)
• [ ] Improve UX for starting without internet connection (what happens if start fails, is there a try again button?)
• [ ] welcome does not show if LND configuration is set in .env
